ERSKINE RAMSAY, OF BIRMINGHAM, ALABAMA.

Specification of Letters Patent.

Patented Sept. "7, 1909.

Application filed June 15, 1903. Serial No. 161,545.

To all whom it may concern:

Be it known that I, ERSKINE RAMSAY, a citizen of the United States, anda resident of Birmingham, Jefferson county, State of Alabama, haveinvented certain new and useful Improvements in Apparatus for ConveyingCoke from Coke-Ovens, of which the following is a specification.

My invention relates to coke ovens and more particularly to apparatusfor conveying the coke drawn or discharged from such ovens directly tocars or other suitable receptacles.

It has been the common practice to draw the coke from the ovens by cokedrawing tools manipulated by workmen standing upon the yard in front ofthe oven doors, the coke falling from the oven doors upon the yard inpiles. It is forked into cars or into barrows and then wheeled intocars, or conveyed to a suitable place of deposit near railroad cars,when there are no'cars and the coke must be stocked, whence it is forkedinto the cars for shipment. In the process of drawing considerable spaceis taken up by the accumulation of the coke in front of the ovens,interfering with the work of the workmen, and much inconvenience anddiscomfort result to the workmen, by reason of the great heat whichrises from the pile of coke, especially in the summer months. Besides,the breeze or ashes is only more or less perfectly separated from thelarger coke, in the forkin operations. This waste left on the yard afterthe coke has been forked must be hauled or carted away and is sometimesused as a waste procluct for fills or ballast by the railroads. It hasbeen proposed to utilize conveyers running in front of the oven doors,onto which the coke is to fall from the said doors as it is drawn fromthe oven by the workmen, but such conveyers, so located, not only takeup considerable room, thereby making it inconvenient for the workmen toproperly draw the charge, as it makes it difficult and laborious to getclose enough for the purpose, but it necessitates the use of a conveyerfor each line of ovens.

By my invention I overcome all the objections noted, since my conveyersare located underneath the platform, and are out of the workmens way,and a single conveyer will serve two lines or rows of ovens, and, actingin conjunction with a main conveyer, will deliver the coke directly fromthe ovens as it is drawn therefrom to railroad cars ready for shipment,or to any other suitable lace.

lVith this object in view, my invention consists in the novelconstruction and the details thereof as hereinafter described, withreference to the accompanying drawings, and more particularly pointedout in the claims.

In the drawings, Figure 1, is a plan view illustrating the applicationof my invention to several batteries of coke ovens; Fig. 2, is anenlarged transverse detail section on the line 2-2, Fig. 1; Figs. 3 and4, are enlarged detail side and plan views of the delivery end of thesupplemental or auxiliary conveyers.

Referring to the drawings, in which the same reference characters relateto the same or corresponding parts in all the views, the numeral 1indicates two batteries of bee hive coke ovens, each comprising doublerows or lines of retorts 31, any suitable number of which may beconstructed with an intervening space between them in which the mainconveyor 4 operates.

As shown in Fig. 2, the bee-hive coke ovens are preferably constructedin pairs each having a retort 31, provided with a door 22, a feed orcharging opening 19 closed by a cover 20 and communicating by a crossfine 17 with the main flue 16, which preferably conducts the waste gasesto a boiler plant, which are there utilized in generating steam. Eachflue 17 is preferably provided with a removable brick damper 18, whichcan be readily dropped into a recess or groove 30 at the junction ofsaid flue with the feed opening 19, thereby cutting off at will anyparticular retort from the main gas flue 16, such cutting off of theretort being very desirable when the oven door is open for watering orcooling and discharge of the coke, the corresponding cover 20 beingremoved during such times, allowing the steam and gases to escapedirectly into the atmosphere during such interval, or at any other timedesired. The top of each double line of ovens is surmounted by asuitable track 21, intermediate two rows of ovens, upon which the carstravel for carrying the coal to the respective ovens for filling thesame. The oven retaining walls are preferably braced by vertical braces24 tied together by transverse braces 25 extending between said verticalbraces 24 on opposite series of ovens.

From each door 22, I extend a chute 23 which is adapted to dischargeinto an auxiliary conveyer 3 located below the platform 2, on the latterof which the coke drawer stands. It will be observed that this conveyeris located below the platform, and in such position as to receive thecoke from any number of ovens constituting opposite rows of ovens inopposite batteries, each such conveyer thus serving two rows of ovens.This conveyer may be of any suitable form, but I have indicated apreferable form in which buckets or pans are carried by traction rollersrunning upon rails 32 supported by beams or cross ties 33, and eachauxiliary conveyer is adapted to discharge its load onto a similarlyconstructed main conveyer at, running transversely thereto on rails 35supported upon beams 34. The delivery end of the main conveyer isarranged to discharge the coke onto a suitable snaking screen 5, alongwhich the large coke travels, freed of the smaller particles, and fallsonto a chute at the delivery end of a similar shaking screen 6,underneath said screen 5, and thence into a car 7, the smaller lumps ofcoke passing through the meshes of the screen 5 onto the screen 6, andsuch smaller lumps as are not finally separated by said screens likewisepassing into the car 7 It is sometimes necessary or desirable to loadthe coke into a box car instead of an open top, and for this purpose Iprovide a suitable chute.

By the use of the conveying apparatus, as herein described, it will beseen that I am not only enabled to load the coke directly into cars fromthe ovens in an expeditious way, without inconvenience or discomfort tothe workmen on the coke drawing platform, but such coke is put into thecars ready for shipment much freer from breeze than by the prior methodsof loading, and a greater percentage of the useful product is saved,while at the same time the smaller particles of separated coke not sentto the cars and heretofore lost are graded into the different commercialsizes all at one operation, and wit-h the least expenditure of time andlabor.

It will be observed that, in the operation of my apparatus, there is noattempt to separate the breeze from the coke at the ovens as has beenthe custom, but it is all carried by the conveyers to the screens, wherethe separation is mechanically and positively effected withoutinterruption to the loading function, and the small coke instead ofbeing wasted as heretofore is discharged from the primary screen intothe grading screen, and there separated into the commercial sizes, theonly loss being the dust.

IVhile I have indicated conventionally shaking screens, it will beunderstood that any suitable kind of screens may be used, and while itis the primary purpose of my invention to effect the loading of the cokeupon cars, it will be understood that the use of my apparatus to conveythe coke to some desired point or bin is within the scope and spirit ofmy invention. Ftlltl'lBll'llOl'G, my improved conveying apparatus may beused in connection with coke ovens of other form than the bee-hive, thelatter being selected as a familiar type to which my invention may bereadily adapted.

I claim as my invention:

1. In an apparatus for conveying coke from a coke oven, the combinationwith adjacent rows of coke ovens with a platform located between therows of ovens below the plane of the oven doors, having a space betweenits sides and the ovens, a single conveyer centrally located beneatheach platform, inclined chutes extending from the ovens through saidspace to the conveyer, and a single independent main conveyer travelingunder and at right angles to the first conveyers adapted to receive thecoke and deliver the same to a car or other suitable place,substantially as described.

2. In an apparatus for conveying coke from coke ovens, the combinationof opposite batteries of ovens, platforms between the adjacent rows ofovens having spaces between the sides thereof and the ovens, singleconveyers located centrally under each of said platforms, chutesextending from the ovens through said space for receiving the coke fromthe coke ovens and depositing the same by gravity in said conveyers, asingle independent conveyer traveling transversely to said conveyersbetween the opposite batteries of ovens adapted to receive the coke fromeach of said first conveyers.

In testimony whereof I have signed my name to this specification, in thepresence of two subscribin witnesses.
